Abstract

Disclosed are: an electronic device for a tire which makes it possible to increase an adhesive force of an adhesive and to reduce a waiting time required for developing a sufficient adhesive strength; and a method for attaching the device. The electronic device for a tire according to the present invention is provided with an electronic component for transmitting information on the tire, and a case for storing the electronic component, and is configured to have a plurality of protrusions or at least one groove provided to an adhered surface of the case. This electronic device for a tire is pasted to a rim outer circumferential surface of a wheel by use of an adhesive.

Claims

1. An electronic device for a tire, characterized by comprising:

an electronic component for transmitting information on the tire; and

a case for storing the electronic component,

the device characterized in that a plurality of protrusions are provided to an adhered surface of the case.

2. The electronic device for a tire according to claim 1, characterized in that each of the protrusions has a pyramid shape.

3. The electronic device for a tire according to claim 1, characterized in that each of the protrusions has a grain shape.

5. The electronic device for a tire according to any one of claims 1 to 4, characterized in that a ratio of a surface area of the adhered surface to a projected area thereof is set at 1.1 to 3.0, the projected area being measured when the adhered surface of the case is projected in a direction of adhesion.

4. An electronic device for a tire, characterized by comprising:

an electronic component for transmitting information on the tire; and

a case for storing the electronic component,

the device characterized in that at least one groove is provided to an adhered surface of the case.

6. A method for attaching an electronic device for a tire, characterized by comprising the steps of:

preparing an electronic device which includes an electronic component for transmitting information on the tire, and a case for storing the electronic component, and in which a plurality of protrusions are provided to an adhered surface of the case; and

pasting the case of the electronic device to a rim outer circumferential surface of a wheel by use of an adhesive.

7. The method for attaching an electronic device for a tire according to claim 6, characterized in that each of the protrusions has a pyramid shape.

8. The method for attaching an electronic device for a tire according to claim 6, characterized in that each of the protrusions has a grain shape.

10. The method for attaching an electronic device for a tire according to any one of claims 6 to 9, characterized in that a ratio of a surface area of the adhered surface to a projected area thereof is set at 1.1 to 3.0, the projected area being measured when the adhered surface of the case is projected in a direction of adhesion.

11. The method for attaching an electronic device for a tire according to any one of claims 6 to 9, characterized in that the adhesive is a single-component polyurethane adhesive.

12. The method for attaching an electronic device for a tire according to any one of claims 6 to 9, characterized in that irregularities are formed on a paste region on the rim outer circumferential surface, prior to a step of adhering the electronic device for a tire.

9. A method for attaching an electronic device for a tire, characterized by comprising the steps of:

preparing an electronic device which includes an electronic component for transmitting information on the tire, and a case for storing the electronic component, and in which at least one groove is provided to an adhered surface of the case; and

pasting the case of the electronic device to a rim outer circumferential surface of a wheel by use of an adhesive.
